1. INPUT SENS knobs
These knobs are used to adjust the sensitivity of the
corresponding input jacks. Note that the INPUT SENS 1
knob also adjusts the sensitivity of the GUITAR/BASS jack.
2. PEAK indicators
These indicators allow you to confirm whether or not the
audio being input via the corresponding input jack is
distorting, and they do this by lighting up when the volume
reaches the distortion level of -6 dB. Use the INPUT SENS
knobs to adjust the input sensitivity in such a way that each
PEAK indicator only lights up occasionally when the
corresponding instrument is being played hard.
3. LEVEL CALIBRATION button
When a number of instruments are connected to different
input jacks, you can use [LEVEL CALIBRATION] to
automatically adjust and balance the corresponding input
volumes.
“Automatically adjusting the input volume balance
(Level Calibration)” (p. 258)
4. INPUT SELECT buttons
Use these buttons to select the input source (input jack) that
you wish to record. The indicater of the selected button will
light. If a lit INPUT SELECT button is pressed, it will turn off
and the corresponding input source(s) will be muted.
GUITAR/BASS:
This button is used to select either the GUITAR/BASS jack
for recording guitar or bass or the INPUT 1/MIC 1 jack for
recording from a line-in or a microphone. Note that the
GUITAR/BASS jack will be selected automatically when an
instrument is connected to it.
* When either [GUITAR/BASS] or [VOCAL] is alone selected,
Adaptive Focus (AF) will be activated for recording.
What is AF method (Adaptive Focus method)?
Adaptive Focus is a unique Roland technology that
allows the signal noise (S/N) ratios of AD and DA
converters to be vastly improved.
VOCAL:
This button is used to select the INPUT 2/MIC 2 jack for
recording from a line-in or a microphone.
SIMUL:
SIMUL mode is activated by holding down [GUITAR/BASS]
and pressing [VOCAL]. In this condition, either the
GUITAR/BASS or the INPUT 1/MIC 1 jack will be selected
together with the INPUT 2/MIC 2 jack. In other words, two
inputs will be simultaneously selected. Note that the
GUITAR/BASS jack will be selected automatically when an
instrument is connected to it.
